Stroke Transport Dashboard Description

The goal of the stroke transport dashboard is to give state data managers a way to easily visualize nationally submitted stroke transport data. To achieve this the dashboard gives detailed information on different aspects of our stroke transport data including specific geography, times, and demographic information.

Global Inclusion Criteria

The global inclusion criteria defines the minimum characteristics each event record must meet in order for it to be included in any of the calculations for the Cardiac Arrest Dashboards. For details on each element, its code, and range of values see the  NEMSIS Version 2.2.1 Data Dictionary.

Complaint Reported by Dispatch Visualization

In the top left section of the dashboard there is a visualization to show the distribution of values for Complain Reported by Dispatch.

The scroll bar on the right can be used to view the distribution across all possible complain values. The visualization shows the number of records reporting each complaint value (based on the filtering criteria selected for the dashboard). To filter the rest of the dashboard on complaint reported by dispatch click on the desired bar. To leave the filter click on the bar a second time.

Complaint Reported by Dispatch Definition

Complaint reported by dispatch is defined as Complaint Reported by Dispatch (E03_01). Bar coloring is on a gradient, with darker bars representing more records.

Demographics Visualizations

The visualizations to the right of complaint reported show some demographic information about stroke incidents. The bubble chart shows the distribution across age groups, and the bar chart shows distribution across genders. To filter on age or gender, click on the desired bar or bubble. To leave the filter click on the bar or bubble a second time.

Distance from Destination Visualization

In the middle of the dashboard there is a visualization depicting information about the distance from the incident to the destination. The map shows two different kinds of marks, a star to represent the destination zip code/hospital, and colored circles to represent incident locations. The tooltip for each mark gives some data on stroke events in each given zip code, including distance in straight line miles to the destination, number of records, average transport time, and average scene time. The star marks only give the destination zip code/hospital. To filter the rest of the dashboard on a specific incident location, click on the desired mark. To leave the filter click on the mark a second time.

Distance to Destination Definition

Distance to Destination is defined as the Euclidean distance (as a bird flies) from the centroid of the incident zip code to the centroid of the destination zip code. Mark coloring is on a gradient, with blue representing greater distances, and red representing shorter distances.

Transport Time Visualization

The bottom left visualization shows a bar chart of transport times for the given filters selected. The coloring is on a gradient with darker colors representing more records.

Transport Time Definition

Transport time is defined as the elapsed time interval from “unit left scene” (E05_09) to “patient arrived at destination” (E05_10).

Scene Time Visualization

The bottom left visualization shows a bar chart of scene times for the given filters selected. The coloring is on a gradient with darker colors representing more records.

Scene Time Definition

Scene time is defined as the elapsed time interval from EMS “arrived on scene” (E05_06) to “unit left scene” (E05_09).

Additional Drop Down Filters

In addition to the filtering options in the visualizations, there are a number of drop down filters provided:

  •  Destination Zip Code
  •  CMS Service Level
  •  Unit Dispatch Date

Tableau Toolbar

All Tableau dashboards share the same toolbar at the bottom of the view. Note that while most dashboards will have the same selections, some items may differ based on user permissions.

Undo, Redo, Revert, Refresh and Pause

These selections are found on the left side of the Tableau toolbar and can be used to help navigate the dashboard.


Undo will remove the last selection made, if you have used undo to remove a selection, you can then use redo to return to that selection. Revert returns the dashboard to its original view. Refresh will reload the data on the dashboard subject to any selections made. Pause will stop the dashboard from refreshing as you make selections.

As an example, if you want to make a set of complete selections in a dashboard’s filters, you could use these buttons to speed up the process. Normally, every time a change is made, the dashboard will refresh. If you select “Pause” however, the dashboard will remain the same no matter how many selections you make. Once you have made all your selections, you can select “Refresh” to reload the dashboard based on those selections.

Subscribe, Custom Views, Edit, Share, and Download

These selections are found on the right side of the Tableau toolbar and can be used to interact with the dashboard in external ways.


The Subscribe button allows users to subscribe to a daily or weekly email that will show a static image of the dashboard as well as a link to the view.

You can select either a particular view (tab) or all the views (tabs) available in the dashboard. Under “Email Subscriptions,” you can choose the frequency of emails. In “Subject Line,” you can assign the subject for the emails. As a default, the subscription will be assigned to the email address associated with your NEMSIS account.

Custom Views allows users to save any particular set of filters or selections for quick access later. A user can create their view and then name it and save it either for their own personal use or use by anyone with access to this dashboard. Previously saved views will appear in the custom views tab.

Edit will open the dashboard in the web editor for Tableau. Note that this option is not available on all dashboards and will require some knowledge of how to use Tableau to build and edit dashboards.

Share will provide a couple of options for sharing the dashboard with others, specifically an embed code and a regular HTML link. While you can use the link to share the dashboard with others, please keep in mind that many of the NEMSIS dashboards will require a username and password. Only those with credentials will be able to access them.

The last option is Download. Clicking on the download button opens up several options to download either the workbook, the data within it, or a static image of the view.

Selecting any one of these file types will produce a download of the requested file. Remember that not all options will be available for all dashboards and views.
